The prompt
Model a control knob on a D-shaft potentiometer mounted in a panel, assembled, as 4 separate solids: panel, potentiometer (body, bushing and shaft as one solid), knob, set screw. Frame: the shaft axis is parallel to Y through X=-30, Z=40; the knob is on the -Y side of the panel. Angles are measured about the shaft axis in the XZ plane from +X toward +Z; radii are from the shaft axis. Panel: plate Y=0..3, X=-70..10, Z=0..80, with a Ø10 hole on the shaft axis. Potentiometer (one solid): body Ø24 from Y=3 to Y=15 (against the panel's back face), bushing Ø10 from Y=0 to Y=3 filling the panel hole, shaft Ø6 from Y=0 to Y=-20. D-flat: from Y=-10 to the shaft tip Y=-20 the shaft is cut by a plane 1.5 from the axis whose outward normal points at 225°. Knob (one solid): cylinder Ø30 from Y=-6 to Y=-24 (6 clear of the panel). Twelve grip flutes: semicircular grooves R2 along Y over the full knob length, their centres on radius 15 at 0° + k·30°. Pointer: a raised rib on the front face, 3 wide, Y=-26..-24, running radially from radius 5 to radius 15 along the 45° direction (diametrically opposite the flat). Blind bore Ø6.1 on the axis from Y=-6 to Y=-21. A Ø3 radial set-screw hole at Y=-14 runs from the bore to the knob surface along the 225° direction. Set screw: a plain Ø3 cylinder in that hole, on the 225° line at Y=-14, from radius 1.5 (its flat end bearing on the shaft's D-flat) out to radius 12 (3 below the knob surface).
